1. Info

Kvaliitti WebDoc 3.0 CMS is a proprietary Finnish-made content management system developed by Kvaliitti Oy (http://www.kvaliitti.fi). It is driven by MS SQL Server and ASP. 

2. Abstract

3. Vulnerable files & PoC:

categories.asp, subcategory.asp, document_id, cat_id

This proof of concept example exposes the internal server variable called "@@version":
